Arctic Armor's entry level cover has the strength and durability of covers costing twice as much. Rugged polyethylene scrim and coating means that this cover can withstand winters worst. Arctic Armor covers are U.V. protected so they will last for years in direct sunlight. The coverís black underside retards algae growth and heat sealed seams means a crystal clear pool next spring. This cover comes with loops every four feet to secure water tubes and corner grommets allow for extra tie down in windy areas. The cover is 5 feet longer and wider than the pool size and it is backed by an 8 year warranty.
